Claims (15)

  1. Verfahren zum Konfigurieren einer Paketdatenkonvergenzprotokoll-, PDCP- , Statusmeldung in einem drahtlosen Kommunikationssystem, wobei das Verfahren aufweist:
    Empfangen einer Anzeige von einer oberen Schicht, dass eine Gesprächsweitergabe stattgefunden hat, in dem Empfänger;
    Konfigurieren einer PDCP-Statusmeldung, die folgendes umfasst, durch die PDCP-Schicht in dem Empfänger:
    • einen Indikator, der eine Folgennummer einer ersten nicht empfangenen PDCP-Dienstdateneinheit SDU anzeigt; und
    • eine Bitmap, die Statusinformationen für wenigstens eine PDCP-SDU anschließend an die erste nicht empfangene PDCP-SDU bereitstellt,
    wobei der Indikator ein erstes fehlendes PDCP-Folgennummern-, FMS-, Feld ist, das die Folgennummer der ersten nicht empfangenen PDCP-SDU enthält,
    wobei die wenigstens eine PDCP-SDU ab einer PDCP-SDU nach der ersten nicht empfangenen PDCP-SDU beginnt, und
    wobei die Bitmap gefüllt ist, um anzuzeigen, welche PDCP-SDUs fehlen, und anzuzeigen, welche PDCP-SDUs keine erneute Übertragung benötigen.
  2. Verfahren nach Anspruch 1, wobei in der Bitmap die PDCP-SDUs, die als fehlend angezeigt sind, bezeichnen, ob eine PDCP-SDU nicht empfangen wurde oder empfangen wurde, aber nicht korrekt dekomprimiert wurde.
  3. Verfahren nach Anspruch 1, wobei in der Bitmap die PDCP-SDUs, die als keine Neuübertragung benötigend angezeigt sind, bezeichnen, ob eine PDCP-SDU korrekt empfangen wurde und korrekt dekomprimiert wurde oder nicht korrekt dekomprimiert wurde.
  4. Verfahren nach Anspruch 2, wobei ein '0'-Bit in der Bitmap anzeigt, dass die PDCP-SDU mit der PDCP-Folgennummer = (FMS + Bitposition) modulo 4096 fehlt.
  5. Verfahren nach Anspruch 3, wobei ein '1'-Bit in der Bitmap anzeigt, dass die PDCP-SDU mit der PDCP-Folgennummer = (FMS + Bitposition) modulo 4096 nicht erneut übertragen werden braucht.
  6. Verfahren nach Anspruch 1, das ferner aufweist:
    Übermitteln der in der PDCP-Schicht konfigurierten PDCP-Statusmeldung von der PDCP-Schicht an eine niedrigere Schicht in dem Empfänger; und
    Übertragen der PDCP-Statusmeldung von der unteren Schicht in dem Empfänger an einen Sender.
  7. Verfahren nach Anspruch 6, wobei das FMS-Feld eine Größe von 12 Bit hat, die zwischen einem Protokolldateneinheit-, PDU-, Typfeld und der Bitmap in der PDCP-Statusmeldung angeordnet ist.
  8. Verfahren nach Anspruch 5, wobei die Bitmap aufgrund des Vorhandenseins des FMS-Felds, das die Folgennummer der ersten nicht empfangenen PDCP-SDU enthält, um anzuzeigen, dass eine derartige PDCP-SDU nicht empfangen wurde, kein Bit enthält, das sich auf die erste nicht empfangene PDCP-SDU bezieht.
  9. Vorrichtung zum Konfigurieren einer Paketdatenkonvergenzprotokoll-, PDCP-, Statusmeldung in einem Empfänger eines drahtlosen Kommunikationssystems, wobei die Vorrichtung aufweist:
    - eine Empfangseinheit zum Empfangen einer Anzeige von einer oberen Schicht, dass eine Gesprächsweitergabe stattgefunden hat;
    - eine Konfigurationseinheit zum Konfigurieren einer PDCP-Statusmeldung, die umfasst:
    • einen Indikator, der eine Folgennummer einer ersten nicht empfangenen PDCP-Dienstdateneinheit SDU anzeigt; und
    • eine Bitmap, die Statusinformationen für wenigstens eine PDCP-SDU anschließend an die erste nicht empfangene PDCP-SDU bereitstellt,
    wobei der Indikator ein erstes fehlendes PDCP-Folgennummern-, FMS-, Feld ist, das die Folgennummer der ersten nicht empfangenen PDCP-SDU enthält,
    wobei die wenigstens eine PDCP-SDU ab einer PDCP-SDU nach der ersten nicht empfangenen PDCP-SDU beginnt, und
    wobei die Bitmap gefüllt ist, um anzuzeigen, welche PDCP-SDUs fehlen, und anzuzeigen, welche PDCP-SDUs keine erneute Übertragung benötigen.
  10. Vorrichtung nach Anspruch 9, wobei in der Bitmap die PDCP-SDUs, die als fehlend angezeigt sind, bezeichnen, ob eine PDCP-SDU nicht empfangen wurde oder empfangen wurde, aber nicht korrekt dekomprimiert wurde.
  11. Vorrichtung nach Anspruch 9, wobei in der Bitmap die PDCP-SDUs, die als keine Neuübertragung benötigend angezeigt sind, bezeichnen, ob eine PDCP-SDU korrekt empfangen wurde und korrekt dekomprimiert wurde oder nicht korrekt dekomprimiert wurde.
  12. Vorrichtung nach Anspruch 10, wobei ein '0'-Bit in der Bitmap anzeigt, dass die PDCP-SDU mit der PDCP-Folgennummer = (FMS + Bitposition) modulo 4096 fehlt.
  13. Vorrichtung nach Anspruch 11, wobei ein '1'-Bit in der Bitmap anzeigt, dass die PDCP-SDU mit der PDCP-Folgennummer = (FMS + Bitposition) modulo 4096 nicht erneut übertragen werden braucht.
  14. Vorrichtung nach Anspruch 9, wobei das FMS-Feld eine Größe von 12 Bit hat, die zwischen einem Protokolldateneinheit-, PDU-, Typfeld und der Bitmap in der PDCP-Statusmeldung angeordnet ist.
  15. Vorrichtung nach Anspruch 9, wobei die Bitmap aufgrund des Vorhandenseins des FMS-Felds, das die Folgennummer der ersten nicht empfangenen PDCP-SDU enthält, um anzuzeigen, dass eine derartige PDCP-SDU nicht empfangen wurde, kein Bit enthält, das sich auf die erste nicht empfangene PDCP-SDU bezieht.
